摘　　要：提出一种基于高阶理论的高精度层合梁单元 ,该高阶理论满足层间位移、应力连续条件 ,由此建立的梁单元具有列式简单。Based on the higher order shear deformation theory, which satisfies the geometric and stress continuity conditions at interfaces, a composite laminate beam element is proposed. The present solutions are compared with those obtained using the three dimensional elasticity theory. Numerical results show that the present element has higher computational efficiency and higher accuracy.
